Anyway it turned out nicely along with the front grill piece which I rebuilt with new slats across the front, veneered in the same wood as the sides.
So all I need now is the amp, so I can get the machine up and running, and the front metal pieces so I can reassemble the front of the jukebox.
The AMI J is also coming along. I made a new wiring loom for the lighting circuit (AMI mains wiring is notorious for rotting) and put back as many parts as I can before the chrome comes back. I need to concentrate on the actual mechanism now before the chrome comes back.
